RESUMO

We describe a 20-year-old man diagnosed with a myelodysplastic syndrome (MDS), admitted to our hospital due to pancytopenia and fever of undetermined origin after myelosuppression with chemotherapy. Disseminated aspergillosis (DIA) was suspected when he developed skin and lung involvement. A rapidly growing mass was detected on the left neck area, during hospitalization. A thyroid ultrasound reported a 3.7 × 2.5 × 2.9 cm oval heterogeneous structure, suggestive of an abscess versus a hematoma. Fine needle aspiration of the thyroid revealed invasion of aspergillosis. Fungal thyroiditis is a rare occurrence. Thyroid fungal infection is difficult to diagnose; for this reason it is rarely diagnosed antemortem. To our knowledge, this is the 10th case reported in the literature in an adult where the diagnosis of fungal invasion to the thyroid was able to be corroborated antemortem by fine needle aspiration biopsy.

RESUMO

Amiodarone is used in a large number of cardiac conditions. Amiodarone-induced thyroid dysfunction has been reported to affect up to 20% of users. Amiodarone can lead to both amiodarone-induced hypothyroidism (AIH) and less commonly amiodarone-induced thyrotoxicosis (AIT). There are two main forms of AIT. Type 1 AIT, a form of io-dine-induced hyperthyroidism, and type 2, a drug-induced destructive thyroiditis. Type 1 AIT develops on individuals with underlying thyroid disease. Treatment of Type 1 AIT includes the use of antithyroid drugs and discontinuation of amiodarone. Type 2 AIT is commonly self-limiting in nature. In this article wedescribe a patient with Amiodarone-induced thyrotoxicosis discussing its clinical features and medical therapeutic approach.

RESUMO

Nontoxic goiter is a diffuse or nodular enlargement of the thyroid gland that does not result from an inflammatory or neoplastic process and is not associated with abnormal thyroid function. Familial forms of goiter in areas not known to feature iodine deficiency are much less common. However, not all individuals in the same iodine deficiency region develop goiter and iodine supplementation does not prevent goiter development in all treated individuals. The etiology of euthyroid goiter is still incompletely understood. It is assumed that the development of goiter depends on various interactions between genetic and environmental factors. We present an overview on the thyroid physiology, which is important for a better understanding of Familial Euthyroid Multinodular Goiter.

RESUMO

Una familia que comprende un período de dos generaciones fue evaluada y el diagnóstico de hiperplasia adrenal congénita de surgimiento tardío confirmado. El caso testigo con la variante atenuada de hiperplasia adrenal congénita presentó con hirsutismo y acné. Sus padres y el hermano menor estaban asintomáticos (variante críptica) mientras que el otro hermano demostró no tener la enfermedad. La respuesta hormonal de los miembros de la familia a Cortrosyn (ACTH) se describe y la importancia de esta prueba para confirmar el estado heterozigótico es enfatizado. La tipicación del antígeno de histocompatibilidad (HLA) en la familia demostró la presencia de B14 el antígeno más comunmente asociado a las mutaciones menos severas de hiperplasia adrenal congénita de surgimiento tardio

RESUMO

Cuarenta y tres pacientes con nódulos sólidos- "frios" del tiroides fueron sometidos a aspiraciones con aguja fina. Se obtuvo material adecuado en todos los pacientes. Las muestras se tiñeron con el método de Papanicolaou y se clasificaron en cinco grupos de acuerdo al grado de cambios atípicos observados. Todos los pacientes fueron sometidos a cirugía independiente de hallazgos "benignos" o "malignos". La correlación patológica demostró una sensibilidad para la prueba de 93% y una especificidad de 79%
